5 RESILIENT WHEEL;

Application filed August 5 -1915. Serial No. 43,764;

To all whom it may concern Be it known that we, CHARL r is RIOEiandTHUniirAN RICE, both citizens of the United States, residing atEas'tSparta, in 5 the county of Stark and State of Ohio, and Canton, in thecounty'of Stark and State of Ohio, respectively, have invented a new anduseful Resilient Wheel, of which the following is a specification.

This invention relatesto resilient wheels and has'more especialreference to that type of resilient wheel which is provided with a Theobject ofoiir invention is to provide a wheel of the characterreferredto, the construction of which will reduce the jar upon resilient wheel,possessing the advantages above mentioned which will be simple, in

construction, inexpensive to manufacture and durable and efficient inuse.

-A further object is tovprovide a wheel of this construction in which.there will be practically? no noise or rattling caused bypartsrduringthe movement of the several the operation of the wheel,

" \Vith these objects in view the invention consists in thenovel-constructionand arrangeinent' of parts, hereinafter described,-

The annularcase a ing 4, the form of which'is ,best illustrated in Fig. 2 islocatedaround the fell-y and connected thereto by means of the series ofbolts 5 which pass through. said casing and i through enlargedapertures-.6 located in the venting any rattling ofthe casing.

The rounded extremities of the screws23'are' opposite face for-thepurposeof receiving one extremity of the cylindrical resilient member28, said resilient member being preferably composed of soft rubber. Thelower extremity of said resilient member is located through the annularrocking member 19 and through the central aperature 17 e posed of softrubber or similar material is.

ocated in the annular depression 22 which is provided around theperiphery of the easmg.

With the construction above described, the

- coil springs 29 cushion the wheel while the resilient members 28prevent excessive compression of said coil springs thus adding a furthercushioning effect to the wheel. Owing to the construction by which therim or casing is connected to the telly only by means of the bolts. 5which pass through the enlarged apertures 6 in the lugs carried upon thefelly, said bolts are free to move in any direction in said apertures,thus allowing a slight rockingmotion of the cushion members when thewheel is suddenly started or stopped, said cushion members rockingbetween the pivotal points 23 and the V-shaped teeth 21.

The adjusting screws not only provide means by which the springs may beadjusted to center the rim or casing with relation to the axis of thewheel but they also enable the tension of the spring to be adjustedaccording to the weight desired to be imposed upon the wheel.

For the purpose of convenience the casing 4. is made of a plurality ofsections riveted or otherwise attached together as illustrated in Fig. 1of the drawings. By the construction of cushion members disclosed hereineach cushion member comprises a double pivoted spring, pivotallyconnecte to the telly and to the casing at its opposite extremities. Asbest shown in Fig. 2 each reaccompanying adjusting plate, the upperextremity of said resilient member being spaced away-from the disk 26and arranged to be received within the socket 27 of said disk when theaccompanying spring 29 is put under pressure, thus relieving the springof a part of the weight or strain and at the same time producing thedesired cushion ef fect. The bolts 5 will come into action where thereis any difiiculty in starting the wheel, contacting with the walls ofthe apertures 6 and causing the tire or casing to move circumferentiallywith the telly.

\Ve claim:

In a vehicle wheel comprising a folly and an annular casing surroundingsaid folly, a set of cushioning devices spaced radially aromntthe wheeland located between the felly and the casing, an adjusting plateprovided with a central aperture laterally disposed V-shaped grooves inthe upper face of said plate and sockets in the lower face of saidplate, adjusting screws located through screw threaded apertures in saidfelly, the extremities of said screws being received within the socketswithin said adjusting plate. an annular rocking member provided with aninternal annular shouhler, V-shaped teeth provided upon the lower faceof said rocking member and located within the V-shaped grooves withinsaid adjusting plate, a cylindrical resilient member located through thea )erture in said. plate and resting upon the ielly, a disk providedwith a socket. said socket receiving the upper end of said resilientmember, said disk provided in its upper face with a rounded socket, apinattached to the inner face of said casing, the extremity of said pin located in the rounded socket of said disk and a coil spring interposedbetween said rocking member and said disk.

In testimony that we claim the above, we

have hereunto subscribed our names.
